    Have you tried to start it with it unplugged? On 1g, I just unplugged the connector and I don't need to push in the pedal.

    He's trying to disable the nuetral safety switch on an automatic for a manual transmission swap. Your talking about the clutch switch, so you can start you car without pushing the clutch down.

    From the '99 Mitsu Eclipse NT A/T diagrams: Connect the black/yellow wire on pin 5 to ground. Try hard to connect to a real ground. If you absolutely can't find one (absolutely last resort and not recommended), connect it to the gray/blue wire on pin 3 (this goes to ground inside the EATX-ECM for the two A/T speed sensors ground which is not the best choice due to: the higher starter relay current through the extra wire traveled and because it's through a separate unit instead of directly to ground).

    Yep (if you're going to keep using the A/T wiring harness on the starter relay).

    ok so i went and looked at the plug and there is no yellow black wire or grey wire.

    Here is thow the plug wires are arranged if your looking at it from the front.

    blue/white|green/black|yellow with brown dots|yellow white|yellow|
    Red|blue

    I don't see any plug like that in my diagrams. If you have the A/T NT harness, you can instead just ground the black/yellow wire (pin 1) of the plug on the starter relay. Don't cut it as it goes to other things that need the ground. Just splice into it and connect to ground.

    Will just grounding that wire on the starter put any stress on any other components?

    Also can someone tell me if i just plug those radiator hoses since they are not needed on the manual tranny

    It will tell the PCM that you are in park or neutral assuming you have the A/T harness and the A/T PCM.

    I think things are getting complicated here and I need clarity. What EXACTLY are you trying to do? Are you replacing the A/T with a M/T? If so, are you replacing the wiring harness for a M/T also? I think you may have to since the M/T ECU is different than the A/T PCM. Also the starter relay for a M/T is wired differently than the one for an A/T even though they are the same relay. Are you also trying to add a turbo? PM me with these answers and tell me everything you're trying to do from what to what.

    Just to straighten everything out. In order to bypass the nuetral safety swith on a 420a engine when doing the auto to manual swap, you must ground the small black/yellow wire that comes off the starter relay behind the radio dins.

    That plug that i have in an earlier post was actually to send spark to the spark plugs(wow do i feel dumb).

    So i now have everything buttoned up and am now adjusting the shift linkages. 5 speeds are so much more fun than autos!

    btw: Why do you want to disconnect it? What is the purpose of starting the car w/out the clutch?
    If it's in gear you will just fly forward...
    If it is in neutral then you don't need the clutch to start it anyway? At least in my last 1g it was like that?

    Explain
